The touch pad is novel in structure, simple and practical, does not need to be complicatedly machined, is lower in cost, is closer for the touch distance of fingers and the sensing layer, is higher in sensitivity and precision and increases the market competitiveness of products.
Description
Technical field
The utility model relates to notebook computer, relates in particular to the Trackpad that uses as a kind of input equipment at notebook computer.
Background technology
Computer industry development in this year rapidly, add the progress of semiconductor fabrication, make the various usefulness of notebook computer be able to run neck and neck with desktop computer, add the volume advantage of notebook computer, the user gives up desktop computer gradually and uses notebook computer one after another instead.
Trackpad is as a kind of input equipment of alternative mouse, is used for moving cursor and selects the towing file destination, is installed in the below of keyboard region usually as individual component, and it is little to have a volume, advantages such as simple operation.Trackpad has three kinds of resistance-type, electromagnetic type and condenser types.Resistor type touch control plate need utilize nib application of force on minimum area when operation, the electromagnetic touch-control plate need cooperate the special pen with battery to import.The principle of work of capacitive touch control plate is the moment of utilizing object to touch Trackpad to produce capacitance coupling effect, thereby can be by the change-detection object position contacting of capacitance, therefore capacitive touch control plate needn't be by the input pen of electric consumption, the use of capacitive touch control plate does not need compression point to concentrate yet, so serviceable life is longer.Moreover the composition of capacitive touch control plate is simple, element is few, finished product rate height, makes that capacitive touch control plate cost when a large amount of production is lower.
More and more when the application of capacitive touch control plate, some application may need more accurate detection usefulness.When the spatial resolution increase of capacitive touch control plate, the equivalent capacity of its trace reduces, and in the time of particularly under the capacitive sensing device is arranged at thicker interface, the capacitive sensing device can't monitor capacitance variations more, causes detecting precision and reduces.
The utility model content
The technical problems to be solved in the utility model is: a kind of simple in structure, sensitivity and the high Trackpad of accuracy are provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical matters that solves the utility model adopts is: a kind of Trackpad, display screen cursor displacement in order to the control notebook computer, comprise inductive layer, control circuit board, described inductive layer comprises a plurality of capacitive sensing devices along X-axis and Y direction distribution, an integrated touch-control chip on the described control circuit board, when extraneous human body contact induction layer, the induced signal that touch-control chip detection inductive layer transmits.
According to another embodiment of the present utility model, Trackpad comprises that further described capacitive sensing device is strip, and described capacitive sensing device forms latticed mutually.
According to another embodiment of the present utility model, Trackpad further comprises protective seam, and this protective seam is adhered on the described inductive layer.
According to another embodiment of the present utility model, Trackpad comprises that further described protective seam made by conductive material.
According to another embodiment of the present utility model, Trackpad further is included in and also is provided with data transmission interface on the described control circuit board.
The utility model has solved the defective that exists in the background technology, and the utility model novel structure is simple and practical, does not need complicated processing, and cost is lower, and finger is nearer with the touch distance of inductive layer, and sensitivity and degree of accuracy are higher, have increased the competitiveness of product in market.
